ALFRED VON HEYNE, OF BERLIN, GERMANY. LOCKING DEVICE FOR BOXES AND THELIKE.

To all whom it may concern:

Be it known that I, ALFRED VON HEYNE, subject of the German Emperor,residing at No. 19 Jagerstrasse, Berlin, Germany, have invented new anduseful Improvements in Locking Devices for Boxes and the Like, of whichthe following is a specification.

This invention relates to a locking device for boxes and the like,wherein undercut and preferably dovetailed lugs are adapted to be slidand secured on the lid in corresponding recesses or grooves of thesides.

The invention is essentially characterized by the fact that the lugsenable the box to be opened on two sides at least and in case of need tocompletely extend over the underface of the lid so as to serve asreinforcing battens thereof against damage during trans port andshipment.

Three constructional forms of a box lid locking device according to theinvention are shown in the accompanying drawings by way of example.

Figure 1 is a plan of the first constructional form of the box withpartly inserted lid and adjacent locking screw. Fig. 2 is a bottom viewof the lid of Fig. 1. Fig. 3 is a vertical section according to lineac-x of Fig. 1, but showing in contradistinction to the latter thecomplete locking position and inserted locking screw. Fig. 4 is a planof the second constructional form of the box with lid partly insertedand partly broken away and with adjacent locking screw. Fig. 5 is abottom view of the lid of Fig. 4. Fig. 6 is a vertical section accordingto line yof Fig. 4 but showing in contradistinction to the latter thecomplete locking position and inserted locking screw. Fig. 7 is a planof the third constructional form of the box with partly inserted lid andadjacent look ing screw. Fig. 8 is a bottom view of the lid of Fig. 7.Fig. 9 is a vertical section according to line 2-2 of Fig. 7, butshowing in contradistinction to the latter the complete locking positionand inserted looking screw.

In the first constructional form according to Figs. 1-3, there isprovided on the inner side of the lid a a middle transverse batten bwhich is dovetailed in its two longitudinal sides and adapted to be slidin the box (Z provided with corresponding grooves c. In the lockingposition (Fig. 3), the box may be locked by a screw 0 with fitting f andsealed by a seal or sealing stamp and the like placed Specification ofLetters Patent.

over the former. As the transverse batten I) has the same cross-sectionin its entire length, the sliding path of the lid (4 is equivalent tothe whole length of the transverse batten Z).

In the second constructional form according to Figs. 4-6, there areprovided on the inner side of the lid 9 two intermediate transversebattens h, which are dovetailed on the enlarged endsi of theirlongitudinal sides and adapted to be slid in the box Z provided withcorresponding grooves Ya. In the locking position (Fig. 6) the box maybe locked by a screw m with fitting n and sealed by a seal or sealingstamp and the like placed over the former.

According to the constructional form of Figs. 46 in eontradistinction tothat of Figs. 1-3, the lid 9 according to Fig. 4 may be so placed thatthe end-enlargements i of the transverse battens 72 are located in frontof their corresponding box grooves 7c and the sliding path of the lid 9according to the arrow 1 need only be equivalent to the length of theend-enlargements i.

In the third constructional form according to Figs. 79, there areprovided on the inner side of the lid 0 two external transverse battensp, which are dovetailed on their inner longitudinal sides and adapted tobe slid in the box r provided with correspondingly recessed corners g.In the locking position (Fig. 9), the box may be locked by a screw 8with fitting t and sealed by a seal or sealing stamp placed over theformer.

According to the constructional form of Figs. 7-9 in contradistinctionto that of Figs. 13 and that of Figs. 4-6, the lid 0 may not only beslid in a straight line but also placed according to Fig. 7 in such amanner that in this case, only one corner-groove g engages with itsouter batten p and the complete sliding path of the lid 0 according tothe arrows 2, 3 is then in the form of a circle.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim and wish to secure by Letters Patent is:

1. A box having an open top and provided With a locking portion in oneof its walls, the length of said portion equal to but not exceeding thethickness of said walls, and a ii d for said box having a lockingportion formed to fit the locking portion in said wall, substantially asand for the purpose set forth.

2. A box provided with undercut locking portions disposed in the marginsof its Walls between the ends thereof, said portions having a length notexceeding the thickness of one of said Walls, and a lid having similarlyformed locking portions between its ends and of a length less than theWidth or length of said lid.

3. A box provided with undercut locking portions disposed in the marginsof its Walls and having a length not exceeding the thickness of one ofits Walls, and a lid having similarly formed locking portions of alength less than the Width or length of said lid.

4. A box provided with undercut locking portions disposed in the marginsof its Walls and having a length not exceeding the thickness of one ofits Walls, and a lid for said box having cleats extending across onedimension thereof, said cleats having similarly formed l portionsadapted for engagement and diseii gagement With said box portions.

5. A box provided with undercut box por tions disposed in the margins ofits Walls and having a length not exceeding the thickness of one of itsWalls, and a lid having cleats ex- 2 tending across one of itsdimensions, portions of said cleats having locking portions formedsimilarly to said box locking portions and of a length less than theWidth or the length of said lid. 30

In Witness whereof I have hereunto signed my name this 16th day ofBecember 1908, in the presence of two subscribing Witnesses.
